Leners Patent No. 108,348, dined october 1s, 1870.

The Schedule referred to in these Letters Patent and making part of the same.

to the accompanying drnwing forming pnrt of thisspecification.

My invention relates to screens for doors and windows, to exclude tiles, mosquitoes, eid other insects.. l will first describe my invent-ion in ce niccti'n with all' thatis necessary to n full understanding thereof',

and then clearly point; it out in the claim.

Figure 1 is a front elevation ot' n, wiinlow-screen, nmde according to my improvement.

Figure 2 is ny vert-ical section ol' the sonic.

Figure 3 is a longitudinal section.

Figure 4 Ais a. sectional detail, showing how thc screen-frame muy be held in the window-trame.

-- Figures 5 and 6 show nu' arrangement of screens vwithout sidernils or stile-s; also, a mode ot' holding them in the window-frame.

Figure is n front view ofn part of n screen, showing how the frames may be strengthened :it the eorners, or joints of cross-mils, by angle-plates.

Figures 8 to 11, incluire, show several iorlns of ihejoiuts of the sides, which nre made in two pui-ts, for the reception ot' the screens et two opposite edges between them, for nime-hing them firmly thereto, by rivets or screws [hissing through the :Seid two ports :ind the screen.

Similar letters oi leien inge4 indicate corresponding ports.

fl propose to, ineke the tiles of the i'rznne of two parts, A B, with ogen inc-es, or :any equivalent vorintion of the snd torni, ond clump the opposite edges ot' the wire-cloth (l between rhein, by tiistening the two ports together upon it by nails, rivets, screws, or

other like `rtieles, und in insert the npper and lowercross-rziils l), which nre previously prepared with .w-keri's, for the .receptionot' the other edges ot' the screen between the seid. stiles oder they are relied to the cloth, hy slipping the ends oi' the seid cross-rails previously out to fit the-edges of the Stiles between them, so as to stretch the cloth, nud cause it .-to hold the-frame togetheijwith sufficient l'oroe for ordinnry screens.

The stilcs nrc preferably malle wit-h the grooves E in the edges which beer against the window-trames,

` both for the purpose of seoring them in the window by means of stlips of1 wood or buttons E nailed onto the window-trame, and fitting into the said grooves when the screensare in place, and also by iliciliinting the dressing down'of' the Stiles when litiing them into the window'.

As a rneans'of 'further siunillfying the construction of window endvd'oor-sereens, I propose, in somc'cases, to make useof the stiles or part-s ofthe-d1une, mfr-de and appiiedosshown at. A B, for the cross-rails, np-4 plying them to the lower md'upper edges only, and

fastening them in the window by the curved plates G art/tached'to the window-frames, as shown, and projecting into grooves prep-tired for them in the ends of the rails, as shown iu figs. 5 and G, onto which ribs the said 'rails may be plnced by placing' the notches coincident with the lugs, and pushing them4 along the latter. i

W hen il; may he desirable to :nrnngo these irrunes on hinges, to swing :is in doors, the corners ot the ,ii-:unes muy be further strengthened by the applicartion ot' the :ingle-plates H, which nifty lm readily nailed ou.

The edges of the wnwrloih, which nre Itri-:ingrid in thestrips l), should be folded over and doubled, ns indicated :it l, fig. 2, for the better holding ol' the nails or screws driven through them. Y

Eor intermediate cross-hairs between the sliles, or upper nud lower bnrs, two or more bnrs, N, muy he placedacross the sheet und nailed rogetlu'r.

Hoving thus described my invent' I claim :isnew and desire to secure by Letters Potent- A freine, formed vor" two partys, A B, combined, as described, with w1-e-riotii C and rails l). lo i'orm n screen.
